The die-back of pistachio is one of the most important diseases affecting pistachio trees reducing yield production. In commercial fields, sampling was done from nine different pistachio production areas in Mahvelat, Khorasan Razavi province during 2008-2010. In each orchard, samples were taken from tree branches with canker during spring and summer seasons. Fungal species were identified based...
Species of Botryosphaeria are among the most serious pathogens that affect mango trees and fruit. Several species occur on mangoes, and these are identified mainly on the morphology of the anamorphs. Common taxa include Dothiorella dominicana, D. mangiferae (= Natrassia mangiferae), D. aromatica and an unidentified species, Dothiorella 'long'. The genus name Dothiorella, however, is acknowledge...
DNA sequences from rDNA and protein-coding regions were determined for six Embellisia and two Nimbya spp. and were compared to those from Alternaria, Ulocladium and Stemphylium spp. Sequences determined included rDNA from the nuclear internal transcribed-spacer region (ITS1/5.8S/ITS2) and the mitochondrial small-subunit (mt SSU) and a portion of the glyceraldehyde-3-phosphate dehydrogenase (gpd...
The most serious aerial disease of garlic is leaf blight caused by Stemphylium spp. Geographical variation in the causal agent of this disease is indicated. Stemphylium vesicarium has been reported in Spain, whereas S. solani is the most prevalent species recorded in China. In this study, Stemphylium isolates were obtained from symptomatic garlic plants sampled from the main Spanish production ...
The endophyte Guignardia mangiferae is closely related to G. citricarpa, the causal agent of citrus black spot; for many years these species had been confused with each other. The development of molecular analytical methods has allowed differentiation of the pathogen G. citricarpa from the endophyte G. mangiferae, but the physiological traits associated with pathogenicity were not described. We...
Four new species of the genus Hemicriconemoides (H. californianus n.sp., H. taiwanensis n.sp., H. annulatus n. sp., and H. nitida n.sp.) are described. The range of total length of H. mangiferae is increased on the basis of specimens collected in Israel, Observations on H. mangiferae and H. litchi support the validity of H. litchi as distinct from H. mangiferae.
In 2007 a new Stemphylium leaf spot disease of Beta vulgaris (sugar beet) spread through the Netherlands. Attempts to identify this destructive Stemphylium sp. in sugar beet led to a phylogenetic revision of the genus. The name Stemphylium has been recommended for use over that of its sexual morph, Pleospora, which is polyphyletic. Stemphylium forms a well-defined monophyletic genus in the Pleo...
در تحقیق حاضر که در قالب مطالعه ی فون کنه های هترو استیگمای مرتبط با حشرات در برخی مناطق شمالِ شرق ایران طی سال های 1390 و 1391 انجام گرفت، در مجموع هفت خانواده از 16 خانواده موجود در کوهورت heterostigmatina در مناطق نمونه برداری شده به دست آمد. تعداد گونه های جمع آوری شده 15 گونه از 11 جنس و 7 خانواده است که در این بین، سه گونه برای جهان، یک زیر جنس و 3 گونه (در مجموع 4 گونه) برای فون بندپایان ...
Background and Aims: The study aimed to determine the effectiveness of three medicinal plant extracts on fungi with three methods and to compare methods. Material and methods: This study examined the antifungal properties of cumin (Cuminum cyminum L), ginger (Zingiber officinale Roscoe) and Nafe Venus (Umbilicus intermedius boiss) extracts against fungi including, Aspergillus spp., Penicillium...
Pestalotiopsis mangiferae Coelomycete fungi were used to examine the production of taxol. The taxol isolated from this fungus is biologically active against cancer cell lines were investigated for its antiproliferative activity in human Non Small Cell Lung Cancer A549 cells. The results showed that the methylene chloride extraction of Pestalotiopsis mangiferae inhibited the proliferation of A 5...
